MD2030 Exhaust bolts

Wondering if anyone knows the specs on the exhaust bolts for the MD2030.

I'm replacing the original riser elbow with a custom stainless one and need to change to shorter bolts. I would like to source some new bolts and bring them with me when I head back to the boat.

Anyone know the size and threads?

Re: MD2030 Exhaust bolts

The original riser to heat exchanger bolts are 92 x 8 x 1.25 thread. They are designed to thread into the H/E about 13 mm, so I guess 13 + new flange, gasket and lock washer thickness would equal the new length?
